Our inserts are not intended for individuals who have sensitive or thin skin or women who are pregnant or breastfeeding.
Unlike a sticky bra that is supported by the adhesive, BOOMBA inserts are supported by the clothing, they cannot stay up by themselves. It is crucial to wear them in tight, structured, and fitted tops.

Have augmented breasts? Please check our FAQ section to see if they are suitable for you.

The sizing guide below only serves as a guideline. For the most accurate fit, please measure your garment and contact us.

Kindly take note that Ultra Boost Inserts come in different cup sizes.

Tip: always size down if you're in between sizes for a seamless fit.

Please note, Demi Boosts come in three sizes (small, medium, and large). Size small is suitable for cup sizes AA / A / B / C, size medium is suitable for sizes D / E, and size large is suitable for sizes F / G.

Please note that our inserts are not intended for individuals who have sensitive or thin skin or women who are pregnant or breastfeeding.

Like traditional inserts, BOOMBA inserts need to be used inside clothing. They cannot be used by themselves.

Wear the garment on your body. Tighten the garment if possible for best results.

Stick the inserts onto the inside of your clothing item and not to your skin.

Scoop breasts up and towards the centre to create cleavage.

While scooping, press the insert onto the breasts and press firmly to secure.

Make sure both sides are even in the mirror, adjust if needed.
